• Performing a fuzzy search may retrieve terms with similar spellings: su ((sac ky) or (sai ky)) tang van hoe. ((hieu ve) OR (hieu va)) cam dua ban thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sai ky)) tang van hoe. ((hieu ve) OR (hieu va)) cam dua ban thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (sai ky)) tang van hoe. ((hieu ve) OR (hieu va)) cam dua ban thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (sai ky)) tang van hoe. ((hieu ve) OR (hieu va)) cam dua ban thanh hai cua tre*.
